Dark boomerang shaped UFO hovers over MIA airport then flies upward past arriving airlinerI am not the eye witness, but I questioned closely the controller involved. I was an air traffic controller at Miami International at the time this event occured. I came on duty at 10 o'clock am on this day. The whole facility was buzzing so I asked what was going on. The person I asked said that the midnighters had seen a UFO at the airport early..I did not get the full details for several weeks. The controller was obviously upset over what he had witnessed and refused to talk about it. I waited a few weeks for the right time and when it was quiet I asked this controller to tell me the whole story. Bob said that he working the midnight shift and his relief had arrived up in the tower cab as well as a flight data assistant (three total). They were chatting and one them looked up at the tower radar display. Something was quickly moving across the scope from the north and toward the airport. The observer called out and they all started looking out the windows (it's dark but getting light in the east). To the north something low was covering up the lights on the ground. At this point the UFO is almost over airport. They all saw it as it came to a hover over the commuter ramp, (low, 100 feet or less) which is in the middle of the airport. At this point I stopped the story to ask a question; how big was it? Bob said it was about the size a B-727, which is quite large. He also said that it was dark in color, maybe dark olive. The object hovered over a vehicle and turned on a bright light. There was a ramp person in the vehicle asleep. The ramp vehicles all have radios tuned to the ground control frequency. This person started screaming on frequency for the tower to quit playing pranks. The light stayed on for several minutes. Remember it's getting lighter outside every minute. The light turned off and it continued to hover. Now it's light enough to see detail. The object the rises vertically and passes very close to a an arriving Eastern Airlines A-300. The aircraft was coming in from the south and was on downwind and preparing to land. The pilot asked "what the hell was that?" The controllers said that they did not know. The object continued up to many thousands of feet, but still visible fron the ground. At this point two other controllers were driving into work. One was coming in from the south and the other from the north. They both saw the object ascend and watched it until it stopped. When it stopped it stayed motionless for several minutes and then it started to gyrate wildly. While it was gyrating it had many multi-colored lights flashing. The object performed like this for several more minutes. When it stopped it stayed motionless for several minutes and then suddenly went vertically out of sight. In the the tower things were hectic trying to see if the radar room could see anything and getting the airliner on the ground. While taxiing in the pilot asked if the controllers knew anything more and then stated "well I guess I've seen one now". Over the next hour or so "answers" started coming from various agencies, none of which were accepted by the controller witnesses. In the end the FAA told them to say nothing of the event. One final thing, Bob mentioned that for the next couple of hours (no wind) a yellow-green haze was seen to stay in the area where the object was hovering.This event was a catalyst, of sorts, to open a host of stories from other controllers. All very interesting.You can e-mail or call for more details if you wold like.((NUFORC Note: Date is approximate. PD))
